The Council of India was the name given at different times to two separate bodies associated with British rule in India.
The original Council of India was established by the Charter Act of 1833 as a council of four formal advisors to the Governor-General at Fort William. The Governor-General in Council was subordinate only to the East India Company's Court of Directors and to the British Crown.
In 1858 the Company's involvement in India's government was transferred by the Government of India Act 1858 to the British government. The Act created a new governmental department in London (the India Office), headed by the cabinet-ranking Secretary of State for India, who was in turn to be advised by a new Council of India (also based in London). In consequence, the existing council in India was formally renamed by the Act (s. 7) as the Council of the Governor General of India.

The 1773 Act provided for the election of four counsellors by the East India Company's Court of Directors. The Governor-General had a vote along with the counsellors, but he also had an additional casting vote. The decision of the Council was binding on the Governor-General. The Council of Four, as it was known in its early days, did in fact attempt to impeach the first Governor-General, Warren Hastings, but in his subsequent trial by parliament he was found to be not guilty.
In 1784, the Council was reduced to three members; the Governor-General continued to have both an ordinary vote and a casting vote. In 1786, the power of the Governor-General was increased even further, as Council decisions ceased to be binding.
The Charter Act 1833 made further changes to the structure of the Council. The Act was the first law to distinguish between the executive and legislative responsibilities of the Governor-General. As provided under the Act, there were to be four members of the Council elected by the Court of Directors. The first three members were permitted to participate on all occasions, but the fourth member was only allowed to sit and vote when legislation was being debated.
In 1858, the Court of Directors ceased to have the power to elect members of the Council. Instead, the one member who had a vote only on legislative questions came to be appointed by the Sovereign, and the other three members by the Secretary of State for India.
The Council of the Secretary of State, also known as the India Council was based in Whitehall. In 1907, two Indians Sir Krishna Govinda Gupta and Nawab Syed Hussain Bilgrami were appointed by Lord Morley as members of the council. Bilgrami retired early in 1910 owing to ill-health and his place was taken by Mirza Abbas Ali Baig. Other members included P. Rajagopalachari (1923-1925), Malik Khizar Hayat Tiwana (1924-1934) and Sir Abdul Qadir
The Secretary of State's Council of India was abolished by the Government of India Act 1935.
